Morgan County Prosecutor Steve Sonnega stated Vandagrifft faces the more serious charges because she knows the boy's history of problems and Boulden didn't.

The 11-year-old faces a September trial in juvenile court.

A probable cause affidavit states Vandagrifft and Boulden left the 11-year-old to watch Andrew as they went to Indianapolis for work on June 30th.

The 11-year-old first told investigators that he heard a pop while in the bathroom and found his brother in a bedroom with a gunshot wound to his head.

He later admitted to investigators that he asked Andrew to clean his room and when he said no, he retrieved a .22 caliber rifle from his parent's room and tried to scare his brother and the gun went off.

The probable cause affidavit also states the boys 9-year-old sister told investigators that the 11-year-old had threatened to kill all three children with a gun or knives on numerous occasions for not doing chores for him.

The girl also said she attempted several times to tell their parents but they did not intervene.
